<p>“One of my top” when you are asking to get off the waiting list over someone who says it is THE top choice? no. If you can’t say “my top”, then just say you remain extremely interested.</p>
<p>Do NOT send any supplemental materials that are not top notch. Did you already send supplemental material? If so, I’d say not to send any more. Just a carefully written letter with interest expressed and any updates since your application. If you didn’t send supplemental materials, then maybe the piece you won a prize for.</p>
